It requires Loopy's PowerPak hacked FDS BIOS. I included a disksys.xdelta patch in the release directory that should work on the original BIOS to create the PowerPak version (CRC32 before patch=5E607DCF, after patch=68D2D988).

Before patch the CRC is correct.
after patch CRC=93B3BD15
and patched BIOS doesn't want to load anything and doesn't report any error. So, it pretends there is no disk loaded.

FDS BIOS patch is now integrated. Now you have to load original BIOS.

I've spent the afternoon playing with the NES core with the added FirebrandX colour palettes and FDS games. Very impressive stuff, especially when added in the VCR6 sound for the Japanese Castlevania 3. I'm seriously considering cashing in on my NT Mini :)

@GreyRogue - while trying various things out I've come across two games that I can't make work, namely Lagrange Point & Tiny Toon Adventures 2 (both Japanese). Both of these games make use of Konami's VCR7 sound expansion. Is this implemented in the Nes core?

Ok. Relatively straight forward. Added VRC7 (mapper 85). No external sound though (only affects Lagrange Point), as that's quite a bit more complicated.

May be call it cartridge sound to make it less confusing?

A cool feature would be a menu option to select between stereo and mono sound. stereo being the two NES CPU channels separated in left and right (2 square wave and the triangle wave, noise channel)

NES didn't have stereo output, so games didn't position channels to L/R.
